This Sunday, the Open Streets series returns with a car-free day of fun. Throughout the summer, main drags around town will close to cars, opening the streets to cyclists, rollerbladers, and pedestrians. Each installment will feature a variety of things to see and do, including live music, street performers, morning yoga sessions, sidewalk sales, art making, skateboard stunts, and plenty of fun people-watching. Things kick off this weekend on Lyndale Avenue South, and other stops this summer include street parties along Lake and Minnehaha (July 21), northeast Minneapolis (August 4), Franklin Avenue (August 25), on the U of M campus (September 8), along West Broadway on the North Side (September 14), and on Nicollet Avenue South (September 22).
